The process open loop auxiliary reference mode P1.00 is selected as follows:
0: none; 1: AI1; 2: AI2
Such calculations as "add", "subtract", "bias", "max" and "min" are available for main reference value f
and auxiliary reference value f
Through the parameter settings in group P6, the frequency change range of the auxiliary reference can
be reduced to realize the fine tuning function.
The process open loop reference main and auxiliary relation calculation parameter P1.01 is defined as
follows:
0: Main reference + auxiliary reference: The auxiliary frequency reference value is superimposed on the
main reference, the function is "add".
Figure 6−4 Process open loop main and auxiliary reference calculation 0
Open loop combination reference f
1: Main reference − auxiliary reference: The auxiliary frequency reference value is superimposed on the
main reference, the function is "subtract".
Figure 6−5 Process open loop main and auxiliary reference calculation 1
Open loop combination reference f
2: Auxiliary reference−50%: The auxiliary reference value subtracts the bias equal to 50% of the auxiliary
reference full range value. The main reference value is disabled at this time.
